Q.Lemon Tree Leaves
1.5 months after being brought inside for the winter, this lemon tree’s leaves have started to get small yellow spots.
I water it based on touch, typically every other week. I leave it in a room about 67-71 degrees and have a plant light on for 8-10 hours each day.
Is this a disease/fungus?
If so, what can I do to remove and prevent it from coming back?
Your lemon tree could be getting too much water or could have a disease that's causing the leaves to yellow. These articles may help you:
